In the reaction of sodium with bromine, explain which atom is reduced.
atroni [7]

Answer:

The reduced atom is Br.

Explanation:

  • The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
  • The oxidation process is the process in which electrons are lost and produce positively charged ions.
  • The reduction process is the process in which electrons is gained and negatively charge ions are produced.

  • In the reaction of chlorine with calcium:

<em>2Na + Br₂ → 2NaBr, </em>

<em></em>

Na loses 1 electrons and is oxidized to Na⁺. (Na → Na⁺ + e).

Br₂ gains 2 electrons and is reduced to 2Br⁻. (Br₂ + 2e → 2Br⁻).

<em>So, the reduced atom is Br.</em>
